The Force Characteristics of Three-Hinged Arch with Non-Uniform Loads and its Reasonable Arch Axis Calculation

Abstract:

In order to solve the stability and reasonable design technology of arched tunnel in tunnel engineering.Based on the general characteristics of the arch tunnel,build a three-hinged arch structure model with non-uniform loads.Through mechanical analysis,obtained the calculation formula of supporting and internal forces of flat and inclined arch with non-uniform loads,and as a basis to calculate their reasonable arch axis equation by MATLAB software.By describing a instance of tunnel engineering,proved the usefulness and accuracy of this method.It provides a reliable calculation method for stability control and design of arched tunnel in tunnel engineering.
